What is secondary glazing and why is it used?

Secondary glazing insulates and sound proofs a window that it is not possible to replace like in a grade 1 or 2 listed building or because the original windows are such a feature of your building why replace them when we can install secondary glazing on the inside, which will give you just as good if not better insulation and sound proofing than double glazing.

We aim to match all of our secondary glazing inline with your windows so that once installed they are not visible from the outside. We offer a range of different secondary glazing windows to fit and match all existing windows.
